Ratio of complex organic molecules with respect to CH₃OH in S68N. The ratios are shown for a 3′′ region in the red- and blueshifted part of the outflow. The abundance ratios in the hot cores are taken from van Gelder et al. (2020) and Nazari et al. (2021). The error bars mark the lower and upper limit on the ratios, as calculated from the optically thick CH₃OH emission (lower limit) and ¹³CH₃OH (upper limit). All outflow abundances obtained from the band 6 data are at 0.′′45 resolution, except for CH₃OCHO and CH₃CN, which were derived from band 3 data at 3′′ resolution.
